Help with playing .avi's with QT

[takehiko]

okay, i am new here, so i hope this is the right forum.
I have some .avi's that are dvd rips. I can play them fine on VLC player but i want to be able to play them on QT so i can export them as ipod movies using moviesformypod. MFMP only works if the .avi file can be played in QT.
When i tried to play the files in QT, there was no sound. The .avi is encoded using codec a52. So i downloaded DivX 5.2.1 and also installed the ac3 codec to try and fix it. Now there is some sound, but it's very choppy and drops out after a few seconds. I have QT 7.0.3, and mac osx 10.3.9 nd i was wondering if anyone could help me at all.
Thank you!

I believe the AC3 codec doesn't work with QT 7.02 and later

Anyone, is that right?

There is a re-install for QT 7.01, but you'll have to do the search.

Otherwise you may use an encoder that doesn't rely on QT to decode the source (ffmpeg X comes to mind)

Good luck, sdm.

yes,
although removing 3ivx for some and only using the DIVX 5.21 codec
and the AC3 component has worked. I would simply use VLC
until Apple releases and official fix.

I wonder if Apple doesn't want AC3 playback in QT? Don't ask me why.

I haven't upgraded to QT 7.03 because I like being able to open video files in QT player. I really have never liked VLC.

I'm in the process of ripping/encoding all my dvds for use on my eyehome. (.avi containing Xvid and ac3 has been my choice. Avi/xvid for wide compatablity and ac3 (5.1) because I couldn't bear to lose surround sound).

After encoding I open 'em up in QT player and check a/v sync and video quality.

Sidenote: Mpeg streamclip opens now opens .movs and .avis containing ac3. And its a pretty capable editor too.

Maybe the author of streamclip could make a new QT component to play ac3?

I think I'll see if upgrading to qt 7.03 and removing 3ivx changes anything - like you suggest terryj. I'd like to try downloading itms videos.

Try Divx Doctor. Sometimes audio is compressed in the AVI's and this app will correct that issue.

[terryj]

And most times DIVX Doctor will dump AC3 tracks
because it can't handle them...
Divx Doctor II and AC3

I also use ffmpedX (v0.0.9s, not 9t), and MPEG Streamclip for conversions that sometimes prove difficult. Sometimes I can "save out" a converted audio track and convert the video to something I can drop into iMovie, then drop the audio in as a separate track. From there, it's easy.

[terryj]

Rumple...Why not ffmpegx v0.09t?
build r3 of it fixed many of the problems
r1 and r2 had...?
just curious why you still use v0.09s?

So does this mean i can not burn an avi with ac3 sound to dvd ? I have tried using toast and produced a silent copy ? Plays fine in vlc player? Any ideas anyone

[rumplestiltskin]

Have you attempted to extract the audio to a separate file? You could use bd4go to convert the AC3 to aiff (or other formats). then you can use QT Pro to add that audio track and save as a reference movie (which refers back to the two original files). Drop -that- file into Toast and encoding should then take place. Let us know.
